Description

Technical Field

[0001] The utility model relates to the technical field of LED wall washer lamps, in particular to an intelligent dimming LED wall washer lamp. Background Art

[0002] LED wall washer lights, as the name implies, let the light wash over the wall like water. They are mainly used for architectural decorative lighting and to outline the contours of large buildings. Due to the characteristics of LED energy saving, high light efficiency, rich colors and long life, other light sources of wall washer lights were gradually replaced by LED wall washer lights in 2013. Because of its long strip shape, some people also call it LED linear light. Its technical parameters are roughly similar to those of LED floodlights. Compared with the circular structure of LED floodlights, LED wall washer lights use Puwei waterproof breathable valves to solve the problem of balanced pressure difference and waterproofing inside and outside the lamp. At the same time, the heat dissipation device of the strip structure is easier to handle.

[0003] For example, a Chinese patent (CN209012992U) discloses an LED wall washer lamp, which relates to the technical field of LED lamps. An LED wall washer lamp comprises a lamp body and a light source assembly, wherein the lamp body comprises a shell, the light source assembly comprises a substrate, the shell comprises a bottom wall and two oppositely arranged side walls, the inner sides of the two side walls are provided with partitions protruding toward the inside of the shell, and the partitions extend along the length direction of the shell, the bottom wall and the partitions together form a receiving groove with an opening, the substrate is embedded in the receiving groove, the substrate comprises an upper connecting portion and a lower connecting portion, the upper connecting portion is bonded to the partition, and the lower connecting portion is bonded to the bottom wall. The LED wall washer lamp can solve the problem of the substrate being arched due to local force by bonding the partitions on both sides to the upper connecting portion of the substrate and the bottom wall to the lower connecting portion, and the contact area between the substrate and the shell is increased due to the bonding between the substrate and the shell, thereby accelerating the heat conduction between the substrate and the shell, thereby improving the problem of poor heat dissipation.

[0004] The above scheme also has the following technical defects: the above convenience is not convenient for automatically adjusting the light brightness; the lamp body of the above scheme cannot adjust the light brightness according to actual needs; when stronger light brightness is needed, the light intensity cannot be increased; and when weaker light is needed, the light brightness cannot be adjusted; the adaptability range of the lamp is narrow, and the light intensity cannot be automatically adjusted. Based on this, an intelligent dimming LED wall washer is proposed. Utility Model Content

[0032] The working principle of the above embodiment is:

[0033] The light sensor 5 monitors the intensity of the external light source. When it is detected that the external light intensity is weak, the motor 402 is started, and the motor 402 drives the bidirectional screw 403 to rotate. The bidirectional screw 403 drives the slider 404 to move in opposite directions. The slider 404 drives the connecting rod 405 and the light shielding plate 406 to move away from each other, so that the blocked light can be irradiated. When it is detected that the external light intensity is strong, the motor 402 is started in the reverse direction, and the motor 402 drives the light shielding plate 406 to move closer to each other, thereby blocking the light. When the device needs to be repaired, the handle 807 is pulled, and the handle 807 drives the limit rod 803 to move, and the limit rod 803 drives the movable plate 805 to squeeze the spring 804, and the spring 804 is deformed. At the same time, the limit rod 803 leaves the limit hole, and then the installation leg 2 is pulled out from the connecting groove 808 to repair the device. After the repair is completed, the installation leg 2 is placed in the connecting groove 808, and the handle 807 is released. The limit rod 803 returns to the limit hole under the action of the spring 804 deformation recovery.
